Building Private

A Chrome extension that overlays normalized unit prices ($/oz, $/fl oz, $/ct) directly onto Amazon, Weee and Target product pages, so comparing across mismatched package sizes stops being mental arithmetic. Zero backend dependency is a hard design constraint: inference runs in-browser on WebGPU via transformers.js, falling back to WASM and then to regex-only. Where the store already prints a unit price the extension adopts it instead of recomputing, and the best-value mark is placed so it never covers the store's own deal price.
